. of operation.

Other objects and advantages of the invent1on will appear in the following description, and the novel feature thereof will be particularly pointed out in the claims. I

In the accompanying drawings in which slmilar letters of reference designate corresponding parts, Figure 1 is a side elevation of my device. Fig. 2 is a front elevation of the same with the soap rack removed. Fig. 3

is a sectional View through the line a; a; Fig.

1. Fig. 4 is a sectional view through the line Y Y Flg. 2. Fig. 5 is a perspective view .of the water distributor. Fig. 6 is a perspective vlew of the soap holder.

The main portion of the machine consists of the frame A made of metal or other suitable material, which is supported by the four rollers B B.

Itesting on the upper portion of the frame A is the water tank 0 which is supplied atits upper portion with the tight fitting cover D.

S1tuated immediately in front of the forward rollers B, and extending the entire width of the frame A is the brush E which has bearings in the sides of the frameA. One of the axles for the brush E consists of a screw (e) which is screwed into the wooden core (a) of the brush, the head of the screw being a smooth cylindrical surface bears in a corresponding recess in the frame A'. The other.

of the sprocket chain H, while the inner one F is connected to the larger sprocket wheel F ,which is'situated at the upper portion of the handle I, by means of the sprocket chain H.

In order to regulate the amount of pressure of the brush against the floor I have provided the triangular plates J which are revolubly secured to the axles of the brush, and at their lower portions supply bearings for the forward rollers B. At the remaining vertex of the plate J is situated the thumb screw K which passes through the radial slot Lin the frame A. It will be readily seen that by this construction the rollers B can be raised or lowered thus diminishing or increasing the pressure of the brush on the object which it is desired to scrub or sweep.

Situated on the under forward portion of the tank 0 is the valve Mwhich is operated from 1 the upper portion of the handle I by means of rods or cords M and connections, one of said rods passing through the handle I which is hollow, and terminating at its upper portion in the ring M" through which is intended to pass the finger of the operator. The valve is returned to its normal position, after being opened, by means of the spring (1.

I do not desire to confine my invention to any particular form of the valve M as any one of the many well known forms may be used, neither do I wish to confine my invention to any particular manner of connecting the ring M" with the valve.

, Beneath the Valve M is situated the pan N shown in Fig. 5, the object of which is to distribute the water uniformly over the surface of ,the brush E, the water being communicatedto the trough (m), which contains perforations on its under surface, by means of the radial grooves (m) (m), &c.

In order to prevent the water and dirt from splashing, I have constructed the shield or the rack by means of the U shaped wires (19) in such a manner that the brush E, when revolving brushes against the soap thus thoroughly soaping the brush.

At the ends of the wooden core of the brush are secured circular metal disks R which prevent thread and other foreign substances from gathering around the axles of the brush.

The handle I is secured to the frame in such a manner that its bearings are in the same line with the axle of the sprocket Wheels F F", in order that the handle may be raised or lowered without affecting the tension of the sprocket chain H.

It will be readily seen from the foregoing description that the brush may be easily detached when worn out and another substituted in its place, also that the brush may be revolved when the remaining portion of the machine is stationary, or the brush may be revolved when the machine is moved in either direction.

Extending outward from the large sprocket wheel F is the handle R by means of which the brush is revolved.

The construction and arrangement of the several parts of my scrubbing and sweeping machine being thus made known, the operation and advantages of the same will it is thought be readily understood.

I am aware that changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In an article of the class described, the combination of a frame A supported on rollers, two, of which are vertically adjustable, a water tank 0 supported by said frame, a handle attached to the frame, a brush having bearings in the frame, a pan N, a valve M adapted to admit water into said pan to distribute the same evenly over the surface of the brush, and a splasher removably secured in the rear of the brush, a rack adapted to hold bars of soap secured to the frame in a position directly over said brush and suffrciently near to the same to allow the soap to come in contact with said brush, and means for operating the several parts, substantially as described.

2. In an article of the class described, the combination of a frame A supported on four rollers,two of which are adjustable, a handle I attached to said frame, a brush having bearings in the frame, a rack adapted to hold bars of soap and secured to the frame directly over said brush and sufficiently near to the latter to allow the soap to come in contact with said brush, a pan N, a valve M havlng a rod M attached thereto, and running back to the handle I for convenient engagement, said valve being located over the pan, a splasher removably secured in the rear of the brush, a sprocket wheel in connection w th the brush, rear sprocket wheels, and cha ns engaging said sprocket wheels for transmrttm g motion, one of the sprocket wheels being mounted on the handle I and adapted to be operated by a crank, substantially as described.

3. In an article of the class described the combination of frame A supported on four rollers, two of which are vertically adjustable, a water tank 0 supported by said frame, handie I attached to said frame, brush E havmg bearings in said frame, rack P adapted to hold bars of soap and secured to said frame A in a position directly over said brush and sufficiently near to said brush, as to allow the soap to come in contact with said brush substantially as and for the purpose set forth 4:. In ascrubbing machine, the combination of a frame, a revoluble brush mounted 1n the lower front portion of said frame, triangular plates J revolubly secured to the axle of the brush on opposite sides, forward roll ers B having bearing in the said plates, said frame having a radial slot therein adgacent to said triangular plates, and a set screw passing through said radial slot, and engaglng the said triangular plates whereby the front rollers may be made adjustable rear rollers attached to the said frame, and means for operating the several parts, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
